2007-12-19Interned MainFileID within SourceManager. Since SourceManager is referenced byTed Kremenek
both Preprocessor and ASTContext, we no longer need to explicitly pass MainFileID around in function calls that also pass either Preprocessor or ASTContext. This resulted in some nice cleanups in the ASTConsumers and the driver. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45228 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-17implement enough helper functions to successfully dump out the Chris Lattner
contents of the header map. Look ma, no assumptions about input data here (aka, corrupt header maps can't crash the compiler - crazy thought). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45122 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-17refactor an better comment framework lookup code. This moves it from Chris Lattner
HeaderSearch into DirectoryLookup, as a particular framework lookup is specific to the directory we are currently querying. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45093 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-17as it turns out, frameworks and headermaps are orthogonal. Make this so inChris Lattner
the internal representation. This also fixes a bug where -I foo -F foo would not search foo as both a normal and framework include dir. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45092 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-09Add dumping support for locations, make -dumptokens print out the locationChris Lattner
info of each token. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44741 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-26Added optional pass-by-reference argument "isExact" toTed Kremenek
NumericLiteralParser::GetFloatValue(). Upon method return, this flag has the value true if the returned APFloat can exactly represent the number in the parsed text, and false otherwise. Modified the implementation of GetFloatValue() to parse literals using APFloat's convertFromString method (which allows us to set the value of isExact). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44339 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-17Move token length calculation out of the diagnostics machinery into Chris Lattner
the lexer, where it can be shared. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43090 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-17Add a new type of lexer: a raw lexer, which does not require a preprocessorChris Lattner
object in order to do its thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43084 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-09Make a significant change to invert the control flow handlingChris Lattner
predefined macros. Previously, these were handled by the driver, now they are handled by the preprocessor. Some fallout of this: 1. Instead of preprocessing two buffers (the predefines, then the main source file) we now start preprocessing the main source file and inject the predefines as a "psuedo #include" from the main source file. 2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify Preprocessor::isInPrimaryFile. 3. The driver doesn't have to know about standard #defines, the preprocessor knows, which is nice for people wanting to define their own drivers. 4. This allows us to put normal tokens in the predefine buffer, for example a definition for __builtin_va_list that is target-specific, and a typedef for id in objc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42818 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-09Add two new Token helper functions, "is" and "isNot". This allows us to writeChris Lattner
stuff like this: // If we don't have a comma, it is either the end of the list (a ';') or // an error, bail out. if (Tok.isNot(tok::comma)) break; instead of: // If we don't have a comma, it is either the end of the list (a ';') or // an error, bail out. if (Tok.getKind() != tok::comma) break; There is obviously no functionality change, but the code reads a bit better and is more terse. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42795 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07move IdentifierTable.h from liblex to libbasic.Chris Lattner

2007-10-07improve layering:Chris Lattner
Now instead of IdentifierInfo knowing anything about MacroInfo, only the preprocessor knows. This makes MacroInfo truly private to the Lex library (and its direct clients) instead of being accessed in the Basic library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42727 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07add a hasMacroDefinition() method to IdentifierInfo, strength reduce aChris Lattner
call to getMacroInfo to call it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42725 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-07Remove the PPID bitfield from IdentifierInfo, shrinking it by a word Chris Lattner
(because all bitfields now fit in 32 bits). This shrinks the identifier table for carbon.h from 1634428 to 1451424 bytes (12%) and has no impact on compile time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42723 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07First step to fixing a long lived layering violation: thisChris Lattner
moves the MacroInfo pointer to a side hash table (which currently lives in IdentifierTable.cpp). This removes a pointer from Identifier info, but doesn't shrink it, as it requires a new bit be added. This strange approach with the 'hasmacro' bit is needed to not lose preprocessor performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42722 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07Shrink the builtinID down by 3 bits, allowing all the bitfields toChris Lattner
fit in 32-bits, shrinking IdentifierInfo by a word. This shrinks the total size of the identifier pool from 1817264 to 1634428 bytes (11%) on carbon.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42719 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-07simplify the interfaces to create selectors: getSelector can take any Chris Lattner
number of arguments now and does the right thing, but the nullary/unary accessors are preserved as convenience functions. This allows us to slightly simplify clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42716 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-05Implement DenseMapInfo for Selector, allowing use of DenseMap/DenseSet ofChris Lattner
Selector's instead of requiring void* to be used. I converted one use of DenseSet<void*> over to use DenseSet<Selector> but the others should change as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42645 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-05Layering refinements for selectors (suggested by Chris). Specifics...Steve Naroff
- Add SelectorTable, which enables us to remove MultiKeywordSelector from the public header. - Remove FoldingSet from IdentifierInfo.h and Preprocessor.h. - Remove Parser::ObjcGetUnarySelector and Parser::ObjcGetKeywordSelector, they are subsumed by SelectorTable. - Add MultiKeywordSelector to IdentifierInfo.cpp. - Move a bunch of selector related methods from ParseObjC.cpp to IdentifierInfo.cpp. - Added some comments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42643 91177308-0d34-0410-b5e6-96231b3b80d8

2007-09-30Add a new getLength() method to IdentifierInfo, which relies on a newly addedChris Lattner
method to StringMapEntry. Steve, please use this to remove the strlen calls in selector processing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42481 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-28Add some comments to MultiKeywordSelector, make all methods private, add a ↵Steve Naroff
friend, move some methods around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42456 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-28Yesterday I discovered that 78% of all selectors in "Cocoa.h" take 0/1 argument.Steve Naroff
This motivated implementing a devious clattner inspired solution:-) This approach uses a small value "Selector" class to point to an IdentifierInfo for the 0/1 case. For multi-keyword selectors, we instantiate a MultiKeywordSelector object (previously known as SelectorInfo). Now, the incremental cost for selectors is only 24,800 for Cocoa.h! This saves 156,592 bytes, or 86%!! The size reduction is also the result of getting rid of the AST slot, which was not strictly necessary (we will associate a selector with it's method using another table...most likely in Sema). This change was critical to make now, before we have too many clients. I still need to add some comments to the Selector class...will likely add later today/tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42452 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-27Fix bug in SelectorInfo::getName() - method buffer needs to be passed by ↵Steve Naroff
reference. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42411 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-27Add SelectorInfo (similar in spirit to IdentifierInfo). The key difference ↵Steve Naroff
is SelectorInfo is not string-oriented, it is a unique aggregate of IdentifierInfo's (using a folding set). SelectorInfo also has a richer API that simplifies the parser/action interface. 3 noteworthy benefits: #1: It is cleaner. I never "liked" storing keyword selectors (i.e. foo:bar:baz) in the IdentifierTable. #2: It is more space efficient. Since Cocoa keyword selectors can be quite long, this technique is space saving. For Cocoa.h, pulling the keyword selectors out saves ~180k. The cost of the SelectorInfo data is ~100k. Saves ~80k, or 43%. #3: It results in many API simplifications. Here are some highlights: - Removed 3 actions (ActOnKeywordMessage, ActOnUnaryMessage, & one flavor of ObjcBuildMethodDeclaration that was specific to unary messages). - Removed 3 funky structs from DeclSpec.h (ObjcKeywordMessage, ObjcKeywordDecl, and ObjcKeywordInfo). - Removed 2 ivars and 2 constructors from ObjCMessageExpr (fyi, this space savings has not been measured). I am happy with the way it turned out (though it took a bit more hacking than I expected). Given the central role of selectors in ObjC, making sure this is "right" will pay dividends later. Thanks to Chris for talking this through with me and suggesting this approach. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42395 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-22Use APFloat for the representation of FP immediates, ask the targetChris Lattner
for *which* apfloat to use for a particular type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42234 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-19Remove SelectorTable/SelectorInfo, simply store all selectors in the central ↵Steve Naroff
IdentifierTable. Rationale: We currently have a separate table to unique ObjC selectors. Since I don't need all the instance data in IdentifierInfo, I thought this would save space (and make more sense conceptually). It turns out the cost of having duplicate entries for unary selectors (i.e. names without colons) outweighs the cost difference between the IdentifierInfo & SelectorInfo structures. Here is the data: Two tables: *** Selector/Identifier Stats: # Selectors/Identifiers: 51635 Bytes allocated: 1999824 One table: *** Identifier Table Stats: # Identifiers: 49500 Bytes allocated: 1990316 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42139 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-17Add support for ObjC keyword selectors.Steve Naroff
- Add SelectorInfo/SelectorTable classes, modeled after IdentifierInfo/IdentifierTable. - Add SelectorTable instance to ASTContext, created lazily through ASTContext::getSelectorInfo(). - Add SelectorInfo slot to ObjcMethodDecl. - Add helper function to derive a SelectorInfo from ObjcKeywordInfo. Misc: Got the Decl stats stuff up and running again...it was missing support for ObjC AST's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42023 91177308-0d34-0410-b5e6-96231b3b80d8
